4. Construct the hypothetical phase diagram for metals A and B between temperatures of 600 C and 1000 C given the following information: 1. The melting temperature of metal A is 800 C. 2. The maximum solubility of B in A 5 wt%B, which occurs at 730 C. 3. At 600 C, the solubility of B in A is 1 wt% B. 4. The melting temperature of metal B is 930 C. 5. The maximum solubility of A in B is 8 wt% A, which occurs at 810 C. 6. At 600 C, the solubility of A in B is 4 wt% A. 7. One eutectic occurs at 810 C and 80 wt% B. 8. A second eutectic occurs at 695 C and 48 wt% B. 9. A third eutectic occurs at 730 C and 22 wt%B. 10. One congruent melting point occurs at 915 C and 34 wt% B. 11. A second congruent melting point occurs at 830 C and 67 wt% B-33 wt% A. 12. The intermetallic compound AB exists at 34 wt% B. 13. The intermetallic compound AB3 exists at 67 wt% B-33 wt% A 1000 C 900 C 800 C 700 C 600 C 0 10 20 30 40 60 70 80 90 100 50 wt%B A B
